Micro PID Controller

Therm is a very small PID controller I designed for espresso, coffee roasting, reflow ovens, and a variety of other uses. It is built around a STM32L microcontroller and includes an OLED display, a 5-way navigation joystick, and a USB interface. This board is currently under development, but I’ll post more information when my second revision PCB is fabricated and assembled in the coming months. For more information, check out the Hackaday project page for Therm.
